Before commencing the installation

Disconnect the power supply of the device.

Ensure that the device cannot be accidentally restarted.

Verify isolation from the supply.

Earth and short circuit.

Cover or enclose neighbouring units that are live.

Follow the engineering instructions (AWA) of the device concerned.

Only suitably qualified personnel may work on this device/system.

Before installation and before touching the device ensure that you are free of electrostatic charge.

Connecting cables and signal lines should be installed so that inductive or capacitive interference do not impair the automation functions.

Install automation devices and related operating elements in such a way that they are well protected against unintentional operation.

Suitable safety hardware and software measures should be implemented for the I/O interface so that a line or wire breakage on the signal side does not result in undefined states in the automation devices.

Ensure a reliable electrical isolation of the low voltage for the 24 volt supply. Only use power supply units complying with IEC 60 364-4-41 or HD 384.4.41 S2.

Deviations of the mains voltage from the rated value must not exceed the tolerance limits given in the specifications, otherwise this may cause malfunction and dangerous operation.

Emergency stop devices complying with IEC/EN 60 204-1 must be effective in all operating modes of the automation devices. Unlatching the emergency-stop devices must not cause uncontrolled operation or restart.

Devices that are designed for mounting in housings or control cabinets must only be operated and controlled after they have been installed with the housing closed. Desktop or portable units must only be operated and controlled in enclosed housings.

Measures should be taken to ensure the proper restart of programs interrupted after a voltage dip or failure. This should not cause dangerous operating states even for a short time. If necessary, emergency-stop devices should be implemented.

2 “easy”

Overview “easy” is an electronic control relay with built-in logic, timer, counter and time switch functions. “easy” is a control and input device rolled into one that can perform many different tasks in building and machine applications.

Circuit diagrams are connected up using ladder diagrams, and each element is entered directly via the “easy” display. For example, you can:

Connect make and break contacts in series and in parallel

Connect output relays and markers,

Define outputs as relays, impulse relays or latching relays

Select timing relays with different functions

Assign eight up and down counters

Display any texts with variables,

Track the flow of current in the circuit diagram

Load, save and password-protect circuit diagrams

Models with the type designation “EASY...-...-..-.C(X)” offer an additional four 7-day time switches each allowing up to four On and Off times.

The DC versions can receive analog signals at two inputs and evaluate the signals with eight analog comparators.

If you prefer to wire up “easy” from a PC, then use EASY-SOFT. EASY-SOFT allows you to create and test your circuit diagram on the PC. EASY-SOFT enables you to print out your circuit diagram in DIN, ANSI or “easy” format.

DANGER of electric shock with “easy”-AC unitsWith “easy” NEVER swap over the live (L) and neutral conductor (N) terminals as the interface will then carry the live (L) potential power of 230 V/115 V. There is a danger of electric shock if the plug is not properly connected or if conductive objects are inserted into the socket.

NoteA short current surge will be produced when switching on for the first time. Do not switch on “easy” via Reed contacts since these may burn or melt.

Cable protectionBoth “easy” AC and DC versions require cable protection (F1) rated for at least 1 A (slow).

Connecting the inputs “easy” inputs switch electronically. Once you have connected a contact via an input terminal, you can reuse it as a relay contact in your “easy” circuit diagram as often as you like.

Connect contacts such as push-button actuators or switches to “easy” input terminals.

Connecting “easy” AC outputs

When “easy” is switched on for the first time, its power supply circuit behaves like a capacitor. Use an appropriate device for switching on the power supply and do not use any reed relay contacts or proximity switches.

Neon bulbs with a maximum residual current of 2 mA/1 mA at 230 V/115 V may be connected at I7 and I8.

Two-wire proximity switches have a residual current on 0. If this residual current is too high, the input of “easy” may only detect the 1 signal.

Therefore use inputs I7, I8. An additional input circuit is required if more inputs are used.

Connecting analog inputsInputs I7 and I8 can also be used to connect analog voltages ranging from 0 V to 10 V.

Use screened twisted pair cables to prevent interference with the analog signals.

For short cable lengths, ground the screen at both ends and with a large contact area. If the cable length exceeds 30 m or so, grounding at both ends can result in equalisation currents between the two grounding points and thus in the interference of analog signals. In this case, only ground the cable at one end.

Do not lay signal lines parallel to power cables.

Connecting the outputs The Q output terminals function inside “easy” as isolated contacts.

In the “easy” circuit diagram the relay coils are controlled via the corresponding output relays Q1 to Q4 or Q1 to Q8 (Q6). You can use the signal states of the output relays as make or break contacts in the “easy” circuit diagram to provide additional switching conditions.

The relay or transistor outputs are used to switch loads such as fluorescent tubes, filament bulbs, contactors, relays or motors. Check the technical thresholds and output data before installing such devices (see chapter 11, from page 197.

If inductive loads are not provided with suppressor circuits, only one inductive load should be switched off at any one time so as to prevent the driver blocks from possibly overheating. If in the event of an emergency stop the +24 V DC power supply is to be switched off by means of a contact, and if this would mean switching off more than one controlled output with an inductive load, then you must provide suppressor circuits for these loads (see the following diagrams).

Behaviour in the event of short-circuits/overload Should a short circuit or overload occur on a transistor output, this output will switch off. The output will switch on up to maximum temperature after the cooling time has elapsed. This time depends on the ambient temperature and the current involved. If the fault condition persists, the output will keep switching off and on until the fault is corrected or until the power supply is switched off.

Scanning for short-circuit/overload see chapter 9, from page 187.

Saving and loading circuit diagrams

There are two ways of saving circuit diagrams in “easy” externally:

By saving to a memory card

By saving to a PC running EASY-SOFT.

Once they have been saved, programs can be reloaded into “easy”, edited and run.

All circuit diagram data is saved in “easy”. In the event of a power failure the data will be retained until the next time it is overwritten or deleted.

Memory cardEach memory card contains a circuit diagram which is inserted into the “easy” interface.

The way the memory card works and a description of how to transfer a program to the card is given in chapter 6, from page 126.

EASY-SOFTEASY-SOFT is an optional PC program with which you can create, store, test (simulate) and manage “easy” circuit diagrams.

Completed circuit diagrams are transferred between your PC and “easy” via the connecting cable. Once you have transferred a circuit diagram, simply run “easy” straight from your PC.

Details on the program and transferring circuit diagrams are given in chapter 6, from page 130.

Working with contacts and relays

In “easy” circuit diagrams, the switches, buttons and relays of conventional circuit diagrams are connected up using input contacts and relay coils.

First specify which input and output terminals you wish to use in your circuit.

Depending on the model concerned “easy” has 8 or 12 input terminals and 4, 6 or 8 outputs. The signal states at the input terminals are recorded in the circuit diagram using input contacts I1 to I12 or R1 to R12. In the circuit diagram, the outputs are switched using output relays Q1 to Q8 and S1 to S8.

Complete the small parallel connection and switch “easy” to Run mode via the main menu.

Return to the circuit diagram display.

You are now unable to edit the circuit diagram.

The circuit diagram display performs two functions depending on the mode:

STOP: Create circuit diagram

RUN: Power flow display

Switch on I3.

In the power flow display, energised connections are thicker than non-energized connections.

You can follow a current-carrying connection across all circuit connections by scrolling the display up and down.

If you switch to the circuit diagram display and are unable to modify a circuit diagram, first check whether “easy” is in Stop mode.

I2---U---ÄQ4I3---k

The power flow display will not show signal fluctuations in the millisecond range. This is due to the inherent delay factor of LCD displays.

Coil functions

You can set the coil function to determine the switching behaviour of relay coils. The following coil functions are available for relays Q, M, S, D, “:”

Marker relay M is used as a “flag”. The S relay can be used as the output of an expansion unit or as a marker if no expansion unit is connected. The only difference between them and the output relay Q is that they have no output terminals.

To ensure an overview of all relay states only assign the same coil function once to a relay (ä, S, R). However, retentive coil functions such as ä, S, R can be used several times if required by the circuit diagram logic.

Exception: The coil function can be used properly several times when using jumps to structure the circuit diagram.

Rules for wiring relay coilsUse the contactor or “impulse relay” function once only for each relay coil.

Only use the “latch” (S) and “unlatch” (R) functions once to control each relay in order to ensure greater clarity in the circuit diagram.

Relays with contactor functionThe output signal follows immediately after the input signal, and the relay acts as a contactor.

A function relay is started via its relay coil or by evaluating a parameter. It switches the contact of the function relay according to its function and the set parameters.

In timing and counter relays, it is also possible to change the switching behaviour via the coil function.

Example with timing and counter relays

A warning light flashes when the counter reaches 10. In this example, both relays C1 and T1 are wired.

Current actual values are deleted if the power supply is switched off or if “easy” is switched to Stop mode.Exception: Retentive coils retain signal (see chapter 8, page 156).

Timing relays “easy” provides eight different timing relays T1 to T8 for use as required.

A timing relay is used to change the switching duration and the make and break times of a relay contact. The possible delay times range between 10 ms and 100 h.

Wiring a timing relay A timing relay is integrated into your circuit in the form of a contact. The function of the relay is defined via the parameter display. The relay is started via the trigger input TRG and can be reset via the reset input RES.

To prevent unpredictable switching states, use each coil of a relay once only in the circuit diagram.

At least two elements are needed in the circuit diagram for a timing relay:

A relay contact in the contact field, in this case T2

A trigger coil in the coil field, in this case TT2.

You can also wire up the reset coil RT2 if you wish.

Counter relays “easy” works with counter relays C1 to C8.

The counter relay adds or subtracts pulses and switches if the current actual value is greater than or equal to the setpoint value. Values between 0000 and 9999 are possible.

A counter relay can be controlled via the counting pulse CCx, counting direction DCx and reset RCx relay functions.

Signal diagram:

The relay contact of a counter with setpoint value 6 switches when the actual value is 6 (A). If the counting direction is reversed (B), the contact switches back when the actual value is 5. Without a counting pulse, the current actual value is retained (C). The reset coil resets the counter to 0 (D).

Possible applications include the counting of components, lengths or event frequency.

Wiring a counter relayYou integrate a counter relay into your circuit in the form of a contact and coil. Counter relay C1 receives counting pulses via the count coil CC1. The counting direction can be changed via the direction coil DC1:

DC1 = 0: relay C1 counts up

DC1 = 1: relays C1 counts down

The Reset coil RC1 is used to reset the counter to the actual value 0.

Contact C1 is used to process the result of the counter in the circuit diagram.

To prevent unpredictable switching states, use each coil of a relay once only in the circuit diagram.

Enter at least one contact and a coil in your circuit diagram:

A relay contact in the contact field, in this case C1

A count coil in the coil field, in this case CC1.

You can wire up coils RC1 and DC1 as required.

Select relay contact C1, move the cursor to 1 and press OK.

Determining counter frequencyThe maximum counter frequency depends on the length of the circuit diagram in “easy”. The number of contacts, coils and circuit connections used determines the run time (cycle time) required to process the “easy” circuit diagram.

Example: When using EASY 412-DC-TC with only three circuit connections for counting, resetting and outputting the result via the output, the counter frequency may be 100 Hz.

To determine the cycle time refer to chapter 9 page 178.

The maximum counter frequency depends on the maximum cycle time.

Use the following formula to determine the maximum counter frequency:

fc = maximum counter frequencytc = maximum cycle time0.8 = correction factor

ExampleThe maximum cycle time is tc = 4000 s (4 ms).

Parameters for countersThe parameter display for counters is used to change the counter setpoint value and to enable or disable parameter access.

Each time switch has four channels which you can use to set four on and off times. The channels are set via the parameter display.

The timer has a back-up battery. This means that it will continue to run in the event of a power failure, although the time switch relays will not switch. When the timer is disconnected from the power supply, the contacts remain open. Information on the battery back-up time are provided in chapter 11, page 201.

Example 1Time switch “Ö1” switches on Monday to Friday between 6:30 and 9:00 and between 17:00 and 22:30.

Latching circuitA combination of a series and parallel connection is used to wire a latching circuit.

Latching is established by contact Q1 which is parallel to I1. If I1 is actuated and reopened, the current flows via contact Q1 until I2 is actuated.

Logic table

Latching circuits are used to switch machines on and off. The machine is switched on at the input terminals via make contact S1 and is switched off via break contact S2.

S2 opens the connection to the control voltage in order to switch off the machine. This ensures that the machine can be switched off, even in the event of a wire break. I2 is always closed when not actuated.

A self-latching circuit with wire break monitoring can alternatively be wired using the Set and Reset coil functions.

Relay Q1 is latched when I1 is switched on. I2 inverts the break contact signal from S2 and does not switch until S2 is actuated. In this way, the machine is switched off if or when a wire breaks.

Retain the order in which both coils are wired in the “easy” circuit diagram: wire first the S coil and then the R coil. This means that the machine will be switched off when I2 is actuated, even if I1 is switched on.

You can use a shift register for storing an item of information, e.g. sorting of parts into good and bad two, three or four transport steps further on.

A shift pulse and the value (0 or 1) to be shifted are needed for the shift register.

The shift register's Reset input is used to clear any values that are no longer needed. The values in the shift register pass through the register in the following order.

How does the shift register work?The shift pulse is switched on for exactly one cycle. To do this, the shift pulse is generated by evaluating the change from I1 “off” to I1 “on” – the rising edge.

In this way, therefore, the cyclical processing of “easy” is used to trigger the shift pulse.

When I1 is switched on for the first time, marker relay contact M7 is switched off and the break contact is closed during the first pass through the cycle. Thus, the series circuit consisting of I1, break contact M7 (closed) and M8 is switched on. Although M7 is switched on, this does not yet affect contact M7.

The contact of M8 (make contact) was still open during the first cycle so a shift pulse cannot yet be generated. When the relay coil M8 is activated, “easy” transfers the result to the contacts.

In the second cycle, break contact M7 opens. The series circuit is now open. The contact M8 is switched on from the result of the first cycle. Now, all

the storage positions are either set or reset in accordance with the series circuit.

If the relay coils were activated, “easy” transfers the result to the contacts. M8 is now open once more. No new pulse can be formed until I1 has opened, since M7 is open for as long as I1 is closed.

How does the value reach the shift register?When shift pulse M8 = “on”, the state of I2 (value) is transferred to storage position M1.

If I2 is switched on, M1 is set. If I2 is switched off, M1 is switched off via break contact I2.

How is the result shifted?“easy” activates the coils in accordance with the circuit connection and its result, from top to bottom. M4 assumes the value of M3 (value 0 or 1) before M3 assumes the value of M2. M3 assumes the value of M2, M2 the value of M1 and M1 the value of I2.

Why are the values not constantly overwritten?In this example, the coils are controlled only by the “S” and “R” functions, i.e. the values are retained in on or off states even though the coil is not constantly switched on. The state of the coil changes only if the circuit connection up to the coil is switched on. In this circuit, the marker relay is therefore either set or reset.

The circuit connections of the coils (storage positions) are only switched on via M8 for one cycle. The result of activating the coils is stored in “easy” until a new pulse changes the state of the coils.

How are all the storage positions cleared?When I3 is switched on, all the “R” coils of storage positions M1 to M4 are reset, i.e. the coils are switched off. Since the reset was entered at the end of the circuit diagram, the reset function has priority over the set function.

How can the value of a storage position be transferred?Use the make or break contact of storage positions M1 to M4 and wire them to an output relay or in the circuit diagram according to the task required.

Running light

An automatic running light can be created by slightly modifying the shift register circuit.

One relay is always switched on. It starts at Q1, runs through to Q4 and then starts again at Q1.

The marker relays for storage positions M1 to M4 are replaced by relays Q1 to Q4.

The shift pulse I1 has been automated by the flasher relay T1. The cycle pulse M8 remains as it is.

Stairwell lighting

For a conventional circuit you would need at least five space units in the distribution system, i.e. one impulse relay, two timing relays and two auxiliary relays.

“easy” requires only four space units. A fully functioning stairwell lighting system can be set up with five terminals and the “easy” circuit diagram.

Four such stairwell circuits can be implemented with one “easy” device.

If you use “easy” with a time switch, you can define both the stairwell lighting and the continuous lighting periods via the time switch.

If you use “easy” with analog inputs, you can optimise the stairwell lighting, via a brightness sensor to suit the lighting conditions.

6 Saving and Loading Circuit Diagrams

You can either use the “easy” interface to save circuit diagrams to a memory card or use EASY-SOFT and a transmission cable to transfer them to a PC.

“easy”-X

“easy” models without buttons can be loaded with a circuit diagram via EASY-SOFT or automatically from the fitted memory card every time the power supply is switched on.

Interface

The “easy” interface is covered.

DANGER of electric shock with “easy”-AC units!If the voltage terminals for phase (L) and neutral conductor (N) are swapped over, the connected 230 V/115 V voltage will be present at the “easy” interface. There is a danger of electric shock if the plug is not properly connected or if conductive objects are inserted into the socket.

To close the slot again, push the cover back onto the slot.

Memory card The “easy-M-8K” card for EASY 412 or “easy-M-16K” for EASY 600 are available as accessories.

Circuit diagrams containing all the relevant data can be transferred from the “easy-M-8K” memory card to the EASY 600. A transfer, however, in the other direction is not possible.

Each memory card can hold one “easy” circuit diagram.

Information stored on the memory card is “non-volatile” (the information is not lost when the power is switched off), and thus you can use the card to make a backup copy of your circuit diagram and/or to transfer it to another “easy” device.

Changing parameters “easy” allows you to change function relay parameters such as times and counter setpoints without having to call up the circuit diagram. This is possible regardless of whether “easy” is running a program or is in Stop mode.


Start the parameter display by selecting PARAMETER.

A complete parameter set will be shown. In the example these are the parameters for a timing relay T1.

The following requirements must be fulfilled for a parameter set to be displayed:

a function relay must have been included in the circuit diagram

the parameter set has been enabled for access, indicated by the “+” character at the bottom right of the display.

Use the PARAMETER menu to access and modify accessible parameter sets. Parameter sets for which access is not enabled are not displayed. “easy” therefore allows you to protect parameters with the use of a password.

Use Í or Ú to scroll through the parameter sets. For this the cursor must be located on the identifier of the function relay, in this case T1.

ü w00.00gS n30.00n sTRG dT1 yRES b +

You can enable or disable parameter access using the parameter “+” or “–” characters respectively in the circuit diagram.

Startup behaviour The startup behaviour is an important help during the commissioning phase. The circuit diagram which “easy” contains is not as yet fully wired up or the system or machine is in a state which “easy” is not permitted to control. The outputs should not be controlled when “easy” is switched on.

Setting the startup behaviour

Requirement: “easy” must contain a valid circuit diagram.

Switch to the System menu.

Specify in which operating mode “easy” should start when the power supply is switched on (see the figure at the top of page 149).

The default setting for “easy” is for STOP MODE to be displayed. In other words, “easy” starts in Run mode when the power is switched on.

“easy”-X models can only be started in Run mode.

If “easy” is protected by a password, the System menu will not be available until “easy” is unlocked (see the section Unlocking easy from page 136).

MODE: RUN/STOP is a toggle menu. The menu always displays the operating mode into which you can change.

8 Retention

It is a requirement of system and machine controllers for operating states or actual values to have retentive settings. What this means is that the values will be retained safely even after the supply voltage to a machine or system has been switched off and are also retained until the next time the actual value is overwritten.

Requirements Permitted “easy” modelsRetentive actual values can be set with EASY 412-DC-.. (via the SYSTEM menu) as well as EASY 600 for the following markers and function relays.

Permitted markers and function relaysIt is possible to retentively store (non-volatile memory) the actual values (status) of markers, timing relays and up/down counters.

The following markers and function relays can be set to have retentive actual values:

EASY 412-DC-..

Setting retention Requirement: in this case “easy” must be in Stop mode

Switch to the System menu.

Switch on the Retention function (see figure on page 153 above).

The default setting of “easy” as it is supplied is the display RETENTION ON. With this setting “easy” runs without retentive actual value data, when a valid circuit diagram is present. When “easy” is in Stop mode or has been switched to a de-energized state, all actual values are cleared.

The Retention setting always applies to all of the relays listed. Individual markers or function relays cannot be set retentively.The retentive data of “easy”-X models with a fitted memory card is deleted when the power supply is switched on.

NoteThe retentive data is kept every time the power supply is switched off. Data security is assured for 100 000 write cycles.

If “easy” is protected by a password, the System menu will not be available until “easy” is unlocked (see chapter 7 from page 136).

The menu item RETENTION ON/OFF is a toggle menu. The menu always displays the operating mode into which you can change.

Changing the operating mode or the circuit diagram

When the operating mode is changed or the “easy” circuit diagram is modified, the retentive data is normally saved together with their actual values. The actual values of relays no longer being used are also retained.

Changing the operating modeIf you change from Run to Stop and then back to Run, the actual values of the retentive data will be retained.

Modifying the “easy” circuit diagramIf a modification is made to the “easy” circuit diagram, the actual values will be retained.

Changing the startup behaviour in the SYSTEM menu

The retentive actual values in “easy” will be retained irrespective of the MODE RUN or MODE STOP settings.

NoteEven when the retentive relays M13, M14, M15, M16 (D1 to D8) and the function relays C8, T8 (C5, C6, C7, T7) are deleted from the circuit diagram, the retentive actual values will be retained after the changeover from Stop to Run as well as after the power supply is switched off and on. Should these relays be used again in the circuit diagram, they will still have their former actual values.

Retentive auxiliary relays (markers)

How the retention works

The retentive markers M13, M14, M15, M16, D1 to D8 should be used in conjunction with the following coil functions.

Set S M.., D..

Impulse relay äM.., D..

Reset R M.., D..

It is essential that you note the following points:

Due to the operation of “easy” the make contact will remain closed and the break contact will remain open. If the Reset condition is active when the power supply is switched on, the state of the contact before power on will be retained for one cycle.

This behaviour can result in a flicker effect in a lamp or a solenoid valve.

Be sure to pay close attention to the example circuits for the individual coil functions.

The following coil functions are not permitted:

ÄM13 to ÄM16, ÄD1 to ÄD8

Examples

S/R coil (break contact)Task:In your application you need to remember whether a screw has been inserted or not. When your installation switches on, it is important that a screw which has already been screwed in place is not screwed in again - otherwise there could be permanent damage to the workpiece or the production line even shut down.

NoteWhen the condition for resetting the marker is fulfilled, the marker is reset.

The circuit above functions in the same way as an impulse relay switch. The make contact will remain switched on in the first “easy” cycle if

a coil is actuated by the make contact of a retentive marker (series and parallel connection both apply here too) and

when the power is switched on, the reset condition for this retentive marker is on.

T1 provides the clock pulse. When a time of t = 0.5 seconds is selected the counting period amounts to 2 t = 1 s. One impulse is counted every second.

The up counter C8 switches valve Q1 on via M15 at 3600 counting pulses (3600 s = 1 h).

M15 resets C8 and prepares C8 for the next hour. To stop C8 continuing to count, the break contact of M15 blocks the counting pulses.

T8 is actuated by means of M15. Once T8 has timed out, M15 and T8 will be reset.

In order that both the time elapsed since the last lubrication (counter C8) and also the lubrication pulse remains constant in the event of a power outage, C8, M15 and T8 must be retentive.

9 Inside “easy”

“easy” circuit diagram cycle

In conventional control systems, a relay or contactor control processes all the circuit connections in parallel. The speed with which a contactor switches is thus dependent on the components used, and ranges from 15 to 40 ms for relay pick-up and drop-out.

With “easy” the circuit diagram is processed with a microprocessor that simulates the contacts and relays of the circuit concerned and thus processes all switching operations considerably faster. Depending on its size, the “easy” circuit diagram is processed cyclically every 0.5 to 40 ms.

During this time, “easy” passes through five segments in succession.

How “easy” evaluates the circuit diagram:

In the first three segments “easy” evaluates the contact fields in succession. As it does so, “easy” also checks whether contacts are connected in parallel or in series and stores the switching states of all the contact fields.

In the fourth segment, “easy” assigns the new switching states to all the coils in one pass.

The fifth segment is outside the circuit diagram. “easy” uses this to make contact with the “outside world”: output relays Q1 to Q.. are switched and inputs I1 to I12 are read once more.“easy” also copies all the new switching states to the status image register.

“easy” only uses this status image for one cycle. This ensures that each circuit connection is evaluated with the same switching states for one cycle, even if the input signals “I1” to “I12” change their status several times within a cycle.

How does this affect the creation of the circuit diagram?

“easy” evaluates the circuit diagram in these five segments in order. You should therefore remember two points when you create your circuit diagrams:

The changeover of a relay coil does not change the switching state of an associated contact until the next cycle starts.

Always wire forward or from top to bottom. Never work backwards.

Example: Switching one cycle laterThis is the circuit diagram of a self-latching circuit. If I1 and I2 are closed, the switching state of relay coil ÄQ1 is “latched” via contact Q1.

1st cycle: I1 and I2 are switched on. Coil ÄQ1 picks up.

Contact Q1 remains switched off since “easy” evaluates from left to right.

2nd cycle: The self-latching function now becomes active. “easy” has transferred the coil states to contact Q1 at the end of the first cycle.

Example: Do not wire backwardsThis example is shown in chapter 5. It was used in the section „Creating and modifying connections“ to illustrate how NOT to do it.

In the third circuit connection, “easy” finds a connection to the second circuit connection in which the first contact field is empty. The output relay is not switched.

When wiring more than three contacts in series, use one of the marker relays.

Delay times for inputs and outputs

The time from reading the inputs and outputs to switching contacts in the circuit diagram can be determined in “easy” by delay time.

This function is useful, for example, in order to ensure a clean switching signal despite contact bounce.

“easy”-DC and “easy”-AC units function with different input voltages and therefore also have different evaluation methods and delay times.

Debounce delay times for basic “easy”-DC basic unitsThe debounce for DC signals is 20 ms.

An input signal S1 must therefore be 15 V for at least 20 ms on the input terminal before the switch contact will change from 0 to 1 (A). If applicable, this time must also include the cycle time (B) since “easy” does not detect the signal until the start of a cycle.

The same debounce delay (C) applies when the signal drops out from 1 to 0.

If the debounce is switched off, “easy” responds to an input signal after just 0.25 ms.

Typical delay times with the debounce delay switched off are:

On-delay forI1 to I12: 0.25 ms

Off-delay forI1 to I6 and I9 to I12: 0.4 msI7 and I8: 0.2 ms

Debounce delay times for “easy”-AC basic unitsThe input debounce with AC voltage signals depends on the frequency:

Switch-on delay80 ms at 50 Hz, 66 ms at 60 Hz.

Off-delay forI1 to I6 and I9 to I12: 80 ms (66 ms)I7 and I8: 160 ms (150 ms) with EASY 412-ACI7 and I8: 80 ms (66 ms) with EASY 6..-AC

The corresponding values for 60 Hz are given in brackets.

If the debounce delay is switched on, “easy” checks at 40 ms (33 ms) intervals whether there is a half-wave present at an input terminal (1st and 2nd pulses in A). If “easy” detects two pulses in succession, the device switches on the corresponding input internally.

If this is not the case, the input is switched off again as soon as “easy” does not detect two successive half-waves (1st and 2nd pulses in B).

If a button or switch bounces (A), the delay time may be extended by 40 ms (33 ms) (A).

If the debounce delay is switched off, the delay time is reduced.

Depending on the type of “easy” in use, it is possible to use the internal inputs I15 and I16, R15, R16 to monitor for short-circuits or overloads on an output.

Transfer EASY-TC-DC Memory card EASY..-..-R...:

I16 is added during transfer of the circuit diagram into “easy” from the memory card. I16 appears as I16 and the logical state remains '0' = switched off (make contact).

If I16 is changed in any way, only I1 to I8 can be entered. I16 can be deleted with the DEL button.

Transfer EASY-DC-TC EASY-SOFT (PC)

EASY-SOFT, Version 1.0, cannot process input I16. I16 is deleted during the transfer to EASY-SOFT. EASY-SOFT, Version 1.1, tolerates I16 without editing being possible. I16 is transferred when the circuit diagram is downloaded.

I16 should be evaluated in accordance with the individual application.

The following examples are for I16 = Q1 to Q4. I15 indicates in the same way short-circuits and overloads on Q5 to Q8.

Example 1: Output with fault indication

The above circuit diagram functions as follows:

If a transistor output reports a fault, M16 is set by I16. The break contact of M16 switches off output Q1. M16 can be cleared by resetting the “easy” power supply.

I15, I16 can only be edited with “easy” versions which have transistor outputs.

Example 3: Automatic reset of error signal

The above circuit diagram functions in the same way as Example 2. In addition the marker M16 is reset every 60 seconds by timing relay T8 (on-delayed, 60 s). Should I16 remain in state '1', M16 will continue to be set. Q1 is set briefly to '1' until I16 switches off again.

Expanding EASY 600 You can expand “easy” models EASY 619/621-... locally using the expansion units EASY 618-AC-RE or EASY 620-DC-TE or remotely – using the EASY 200-EASY coupling module.

For this first install the units and connect the inputs and outputs (see chapter 3, Installation).

Incorporate the inputs of the expansion units as contacts in the “easy” circuit diagram like the inputs in the basic unit. The input contacts possible are R1 to R12.

R15, R16 are the central fault inputs of the transistor expansion unit (see also Scanning Short-circuit/Overload on page 187).

The outputs are processed as relay coils or contacts like the outputs in the basic unit. The output relays are S1 to S8.

How is an expansion unit recognised?

When using at least one R contact or S contact/coil in the circuit diagram, the basic unit assumes that an expansion unit is connected.

Transfer behaviour

The input and output data of the expansion units is transferred serially in both directions. Take into account the modified reaction times of the inputs and outputs of the expansion units:

EASY 618-AC-RE provides the outputs S1 to S6. The other outputs S7, S8 can be used as markers.

Input and output reaction times of expansion unitsThe debounce setting has no effect on the expansion unit.

Transfer times for input and output signals:

Local expansionTime for inputs R1 to R12:30 ms + 1 cycle

Time for outputs S1 to S6 (S8):15 ms + 1 cycle

Remote expansion Time for inputs R1 to R12:80 ms + 1 cycle

Time for outputs S1 to S6 (S8):40 ms + 1 cycle

Function monitoring of expansion units

If the power supply of the expansion unit is not present, no connection can be established between it and basic unit. The expansion inputs R1 to R12, R15, R16 are incorrectly processed in the basic unit and show status 0. It cannot be assured that the outputs S1 to S8 are transferred to the expansion unit.

The status of the internal input I14 of the basic unit indicates the status of the expansion unit:

I14 = “0”: Expansion unit is functionalI14 = “1”: Expansion unit is not functional

WarningEnsure the continuous monitoring of the “easy” expansion in order to prevent switching faults in machines or systems.

ExamplePower can be applied to the expansion unit later than the basic unit. This therefore means that the basic unit is switched to Run with the expansion unit missing. The “easy” circuit diagram below detects if the expansion unit is operational or not.

As long as I14 is 1, the remaining circuit diagram is skipped. If I14 is 0, the circuit diagram is processed. If the expansion unit drops out for any reason, the circuit diagram is skipped. M1 detects whether the circuit diagram was processed for at least one cycle after the power supply is switched on. If the circuit diagram is skipped, all the outputs retain their previous state. The next example should be used if this is not desired.

Glossary

Analog input The DC versions of “easy” have analog inputs I7 and I8. The input voltage range is 0 V to 10 V. Input data is evaluated by built-in analog comparator function relays.

Circuit connections Every line in the circuit diagram display represents a circuit connection.

Circuit diagram symbols

As in conventional wiring, the circuit diagram is made up of circuit elements. These include input, output and marker relays, plus function relays and the P buttons.

Connect mode Connect mode is used to wire up the circuit elements in your “easy” circuit diagram.

Contact behaviour The contact behaviour of any circuit element can be defined as either a break contact or a make contact. Break contact elements are identified by a line on top of the identifier (Exception: Jump).

Entry mode Entry mode is used to input or modify values when creating circuit diagrams or setting parameters, for example.

Function relays Function relays are provided for more complex switching tasks. “easy” features the following types of relay:

Timing relays

Time switches

Counters

Analog comparators

Text marker relays

Impulse relay An impulse relay is a relay which changes its switching state and stays changed (latched) when a voltage is applied to the relay coil for a short time.

Input The inputs are used to connect up external contacts. In the circuit diagram, inputs are evaluated via contacts I1 to I12 and R1 to R12.“easy” 24 V DC can also receive analog data via inputs I7 and I8.

Interface The “easy” interface is used to exchange and save circuit diagrams to a memory card or PC.

Each memory card contains one circuit diagram and its associated “easy” settings.

The EASY-SOFT PC software allows you to control “easy” from your PC which is connected using the “easy-PC CAB” cable.

Local expansion I/O expansion with the expansion unit (e.g. EASY 620-DC-TE) installed directly on the basic unit. The connector is always supplied with the expansion unit.

Memory card The memory card is used to store your “easy” circuit diagram, together with its parameter and “easy” settings. Your data on the memory card will be retained, even if the power supply fails or is switched off.

The memory card is inserted into the interface slot on the “easy” device.

Operating buttons “easy” has eight operating buttons. These are used to select menu functions and create circuit diagrams. The large round button in the middle is used to move the cursor.

DEL, ALT, ESC and OK all perform additional functions.

Operating mode “easy” has two operating modes: RUN and STOP. RUN mode is used to process your circuit diagram (with the controller running continuously). In STOP mode you can create your circuit diagrams.

Output You can connect various loads to the four “easy” outputs, such as contactors, lamps or and motors. In the “easy” circuit diagram the outputs are controlled via the corresponding output relay coils Q1 to Q8 or S1 to S8 (Q6).

P buttons The P buttons can be used to simulate four additional inputs which are controlled directly by the four cursor buttons, rather than via external contacts. The relay contacts of P buttons are connected up in the circuit diagram.

Parameters Parameters enable the user to set the behaviour of a function relay. Possible values include switching times or counter setpoints. They are set in the parameter display.

Power supply “easy”-AC is powered by AC voltage at 115 to 240 V AC, 50/60 Hz. The terminals are labeled “L” and “N”.

“easy”-DC is powered by DC voltage at 24 V DC. The terminals are labeled “+24 V” and “0 V”.

The terminals for the power feed are the first three terminals on the input side.

Remote expansion I/O expansion with the expansion unit (e.g. EASY 620-DC-TE) installed up to 30 m away from the basic unit. The EASY 200-EASY coupling unit is fitted to the basic unit. The input and output data is exchanged between expansion and basic unit via a two-wire cable.

Retention Retentive data is kept even after the “easy” power supply is switched off.

The following data is retentive:
